In the DE-STAR lab, we propose to use phased laser array with photon propellant in order to achieve significantly higher speed for the spacecraft. During the simulation, the laser is sometimes turned off to avoid cancellation of force or acceleration. However, if we shut off the laser accurately, the duration rises and drops even when the launch time is altered slightly, which makes the real im...

Developing smart iontronic materials is highly desired for eradicating the widely occurring potential short-circuit hazard and subsequent safety problems caused by high ambient humidity. In this work, a humidity-responsive ionogel (HRIG) based on poly(benzyl methacrylate) matrix swollen hydrophobic ionic liquid hygroscopic lithium salt reported. The HRIG exhibits an anomalous decrease in conduc...

As part of the government response to the Deepwater Horizon blowout, a Well Integrity Team evaluated the geologic hazards of shutting in the Macondo Well at the seafloor and determined the conditions under which it could safely be undertaken. Of particular concern was the possibility that, under the anticipated high shut-in pressures, oil could leak out of the well casing below the seafloor. Su...

Natural gas pipeline networks used for long-distance transportation are expanding quickly, and the construction of special valves with large diameters has especially increased since 2022. The design manufacturing flow control equipment is carried out on a case-by-case basis, in accordance parameters required by beneficiary. In this paper, results obtained fluid simulation SolidWorks2023 softwar...

Electric grid faults can ignite catastrophic wildfires, particularly in regions with high winds and low humidity. In real-time operations, electric utilities have few options for wildfire risk mitigation, leading to use of disruptive measures such as proactive de-energization equipment, frequently referred public safety power shut-offs. Such shut-offs significant impacts on customers, who exper...

Excessive water production in the oil field is major difficulty for petroleum industry. Remedial techniques need to be applied control this excess considering health, safety, and environmental issues improve reservoir's economic productive life. In study polymer gel system comprising partially hydrolyzed polyacrylamide (PHPA) organic cross-linkers (Hydroquinone Hexamethylene tetramine) were pre...

DMSO (dimethylsulfoxide), a potent inducer of granulocytic differentiation in HL60 cells, causes a rapid decrease of cytoplasmic steady state c-myc RNA. This decrease is regulated mainly at the level of transcript elongation. Elongation is blocked within the untranslated c-myc leader. Twelve hours after transcriptional shut off of c-myc, DNAase I hypersensitive site II was still detectable, ind...

Direct evidence demonstrates that urban and industrial air pollution can completely shut off precipitation from clouds that have temperatures at their tops of about -10 degrees C over large areas. Satellite data reveal plumes of reduced cloud particle size and suppressed precipitation originating from major urban areas and from industrial facilities such as power plants. Measurements obtained b...

Using a time-dependent phosphorus (P) budget model for the Baltic proper, describing sources and sinks at the external borders of the water column, one may compute the e-folding time T of the adjustment of the winter surface water P concentration c 1 to abruptly changed total P supply. The restoration time TR = 3T is introduced as a practical measure of the time it takes to achieve 95% of the c...
